These are the Blackbirds.
They were all invented by Kelly Johnson of the Skunk Works.
All four of these aircraft were capable of going Mach.
Three, that’s three times the speed of sound.
The A-12 is the only Blackbird that has one cockpit; all other versions have two cockpits.
The YF-12 held to air-to-air 47 Falcon (GAR-9) missiles. A-12 only held cameras and was owned by the CIA.
The MD-21 was built to launch drones.
The Blackbird that flew the longest was the SR-71 it had a variety of cameras and sensors. It was constantly updated with the latest electronic countermeasures.
The SR-71 flew from 1966 to 1990. She is still the fastest-manned aircraft in the world ~ written by Linda Sheffield
